Definitions

  • the invention relates to a device for processing an end of an electrical cable according to the preamble of claim 1.
  • the invention also relates to a method of machining an end of an electrical cable according to the preamble of claim 8.
  • the invention also relates to a cable assembly system.
  • the processing of the end or ends of the electrical cable can include exposing or stripping the outer conductors and inner conductors, cutting the cable to length in some areas, applying a support sleeve for installing the connector, cutting an outer conductor to length and possibly turning it inside out onto a Support sleeve and / or include the final assembly of the connector.
  • a particular difficulty here is usually the defined cutting of the outer conductor, especially when the outer conductor is designed as a braided cable shield.
  • the processing step of partially cutting the braided cable shield or outer conductor to length manually can be carried out comparatively easily and naturally also flexibly with regard to the desired length of the connecting piece of the braided cable shield.
  • a mechanically automatable method for processing an end of an electrical cable is, for example, from the generic EP 2 912 736 B1 known.
  • the EP 2 912 736 B1 discloses a method in which, by means of a combination of a stamp and a die, the individual strands of a braided cable shield are folded back or inside out during processing, for example onto a support sleeve for crimping with a connector fitted later, with an excess portion or a waste piece of the braided cable shield is automatically severed by shear forces between the punch and the die.
  • This method has proven itself and achieves significant savings in terms of costs and time, especially in mass production.
  • the known method cannot cut a braided cable shield to any desired length, in particular since the braided cable shield is folded back during processing due to the geometry of the device. This means that any lengths cannot be specified without further ado, since the dimensions of the punch and die dictate the length of the remaining braided cable shield. Furthermore, depending on the application, cutting to length in combination with folding over the braided cable shield is not always desired. The known method can therefore not be used universally enough for use with different types of connectors.
  • the present invention is based on the object of providing a device for processing an end of an electrical cable which is particularly suitable for cutting an exposed braided cable shield of the cable to length in a defined manner and thus preparing it for subsequent assembly.
  • the present invention is also based on the object of providing a method for processing an end of an electrical cable, in which an exposed cable shielding braid of the cable can be cut to length in a defined manner, in particular for subsequent assembly.
  • the invention is also based on the object of providing a cable assembly system.
  • the device according to the invention for processing an end of an electrical cable comprises a cutting device for cutting to length an exposed cable shielding in the region of the end of the cable to be processed, in order to cut the cable shielding into a waste piece to be removed and a cut the connector remaining at the end of the cable.
  • the cutting device has a die with a through hole through which the end of the cable to be processed can be passed coaxially.
  • the cutting device also has a punch which can be advanced coaxially to the die in order to cut the exposed braided cable shield of the end of the cable inserted into the die by means of shearing forces between the punch and die.
  • the matrix has a contact surface for at least a partial area of the connection piece of the braided cable shield that remains after cutting to length, against which the partial area of the connection piece rests during cutting to length.
  • the invention is suitable for use with any electrical cable that includes at least one electrical conductor.
  • the electrical cable preferably comprises at least one inner conductor, optionally also two, three, four, five, six or even more inner conductors.
  • the invention is particularly suitable for use with electrical cables whose outer conductor is in the form of a braided cable shield, i. H. as intertwined individual strands or individual wires. For this reason, the braided cable shield is also referred to below as the "outer conductor". However, this is not to be understood as limiting.
  • the invention may be well suited for processing an end of a coaxial cable.
  • the electrical cable can also be regarded as part of the device within the scope of the invention.
  • a portion of the cable shielding braid remaining on the cable during cutting i. H. a particularly simple length adjustment for cutting the braided cable shield to length can be provided while the braided cable shield is being divided into a waste piece and a connection piece, which is in contact with the contact surface of the matrix.
  • the remaining length of the braided cable shield or the remaining connection piece is determined by the dimensions of the die used in combination with the punch used, in this case it can be determined by the positioning of the cable in the die or relative to the contact surface the desired length of the connection piece can be flexibly determined.
  • connecting piece refers to the function of the piece of the exposed cable shielding braid that remains on the cable after it has been cut to length (cutting off the waste piece), which during the assembly or processing of the end of the cable on a connector or a sleeve of a connector etc .can be connected (e.g. for electrical contacting and/or for mechanical strain relief).
  • a further advantage of the invention is that cutting the braided cable shield to length and folding the connecting piece can be decoupled from one another.
  • the braided cable shield can also be cut to length without the braided cable shield then or simultaneously being folded back onto a support sleeve or the like.
  • the invention is particularly suitable for assembling plug connectors in which a braided cable shield does not have to be folded back over a support element.
  • the end of the cable to be processed can be guided coaxially through the through hole of the die along a feed direction.
  • the feed direction can in particular be aligned along the longitudinal axis of the electrical cable.
  • the stamp for dividing the braided cable shield is then fed coaxially to the die counter to the feed direction.
  • the through bore of the die is preferably a central through bore.
  • the contact surface of the die is an inner surface of the through hole of the die.
  • an inner surface of the through hole has proven to be particularly suitable for the contact of the braided cable shield during the cutting to length.

  • the punch can have a correspondingly large bore, the diameter of which is greater than or equal to the diameter of the cylindrical section of the die.
  • the cutting device has a clamping device for fixing the cable in order to fix the cable at least axially (or in or against the feed direction) during the cutting to length.
  • an axial securing of the electrical cable can be possible permanently or only during certain processing steps, for example during cutting to length.
  • the electrical cable can also be secured against twisting, if necessary, by means of the clamping device. Due to the clamping device, the invention can in particular also be particularly well suited for processing an end of an electrical cable that is arranged on a cable drum.
  • the clamping device fixes the cable both torsionally and axially, preferably in a non-positive manner.
  • the clamping device comprises at least two clamping jaws that can be advanced onto the cable.

  • a blunt form knife is preferably used.
  • the pliers-like tool can make the radially circumferential indentations at one, two, three, four, five or even more positions along the braided cable shield that are axially offset from one another.
